Project 2: Mini plant connected to the CDER’s grid

This project is part of the Algerian-Spanish Cooperation. It is a photovoltaic (PV) system with a generator which provides electricity to the grid.

Thus, the system consists of the PV generator and inverters that convert direct current produced into alternating current, this latter is injected in the network (220 volts).

The current produced by this PV system is perfectly compatible with that provided by the network. The PV generator consists of 90 photovoltaic modules I-106, coupled on three inverters Ingecon 2.5 (for contact: hadjarab@cder.dz).
